Abstract
The present invention relates to an ultrasonic welding apparatus including a horn unit including a horn wherein the horn is configured to contact a target to be welded and a vibrator configured to apply vibration to the horn; an anvil unit including an anvil having a first flat surface on which the target to be welded is configured to be placed and a support portion configured to support the anvil in a rotatable state; and a welding main body configured to have the horn unit and the anvil unit fixed thereto, wherein the anvil is rotated in a state of being supported by the support portion such that the first flat surface of the anvil is parallel to a welding surface of the horn, whereby parallelism between the horn and the anvil may be easily achieved, and welding quality may be improved.
